Microwave vacuum drying ovenIt is an efficient and environmentally friendly industrial equipment that combines microwave heating and vacuum drying technology, mainly used for low-temperature drying treatment of heat sensitive materials such as food, medicine, and chemical raw materials.

Structural composition:

Vacuum system: including vacuum pump, vacuum pipeline, vacuum gauge, etc. The vacuum pump extracts the air from the drying box to create a vacuum environment; The vacuum pipeline connects the vacuum pump and the inner chamber of the drying oven for gas transmission; The vacuum gauge monitors the vacuum level inside the drying oven in real-time.

Microwave system: composed of a microwave generator and a waveguide system. The microwave generator converts electrical energy into microwave energy, and the waveguide system guides the microwave to be transmitted from the microwave generator to the drying oven, ensuring uniform distribution of the microwave.

Control system: including temperature controller, vacuum degree controller, time controller, and operation panel, etc. The temperature controller precisely controls the temperature inside the box, the vacuum degree controller maintains a stable vacuum environment, the time controller sets the drying time, and the operation panel is used for operators to set parameters and control equipment operation.

　　Microwave vacuum drying ovenAdvantages:

Low temperature rapid drying: Combining microwave and vacuum technology, materials can be quickly dried at low temperatures of 30-60 ℃, reducing drying time by 50% -70% compared to traditional methods.

High component retention rate: It can effectively retain thermosensitive components in materials, such as medicinal herbs after microwave vacuum drying, with a volatile oil retention rate of over 90% and a polysaccharide loss rate reduced to less than 5%.

Good quality uniformity: Microwave penetration heating can eliminate the temperature difference inside the material, avoid local overheating, and the vacuum environment can also suppress oxidation reactions, maintaining the natural color of the material.

Energy saving and efficient: The drying cycle is short, energy consumption is reduced by about 40%, and the enclosed design reduces dust flying, which meets relevant standards.
